Founder's Biography
Technical Director · Systems Architect · Master Craftsman · Environmental Innovator
John Leah is a seasoned technical leader whose career spans global touring productions, large-scale energy-efficiency programmes, government-level environmental advocacy, digital systems architecture and award-winning craftsmanship.
His professional journey reflects a rare blend of technical mastery, operational leadership, creative problem-solving and a long-standing commitment to sustainability — the same blend that shapes every project Mixture delivers today.
IT Manager and the brand's first-ever Online Marketing Manager. Technical liaison for Screenco and Creative Technology on major events including the 2002 Commonwealth Games and UK SkillCity (attended by HRH Prince Charles).
Led national energy-efficiency delivery and built the first carbon-saving and Google Earth property-mapping system used by ALMOs and Housing Associations. Invited to the House of Commons, Whitehall and the House of Lords.
Represented the North West's green-technology expertise as part of a UK Trade & Investment delegation led by Clive Drinkwater.
Extended the carbon-calculation platform to support Green Deal assessments — integrating funding logic, carbon savings and property-level data.
Technical consultancy, custom systems, brand development and digital strategy for ambitious UK businesses.
Rebuilt and led the technical deployment of the world's first and largest touring VR exhibition across Europe, the Americas and Russia — including a six-week residency with Disney in Los Angeles, CCCB Barcelona, Harpa Reykjavík, CENART Mexico City, CCBB Brasília/Rio/São Paulo, Moscow Biennale, Day for Night (Houston) and Poznań. Trained local crews in every country, often through interpreters.
Built an award-winning bespoke upholstery business — consistently Top 3 in Tameside, accepted into the Guild of Master Craftsmen, and grown four-fold on the back of a cloud-based management system he designed and built himself.
